Paper Abstract

Aluminum-coated optical fibers are loaded with molecular hydrogen by keeping the fibers in an H2 atmosphere at high pressure and temperature. A high H2 concentration in the fiber glass (up to 1 at. %) has been obtained by this technique. A drastic reduction of radiation-induced absorption in the visible spectral region in H2- containing Al-coated fibers is demonstrated. The formation mechanism is the H(I)-center is analyzed.
